EPeS Max Flow HPA Low Pressure Airsoft Regulator

EPeS Max Flow HPA Low Pressure Regulator

MaxFlow HPA Low-Pressure Regulator, two destructive stickers, two Allen keys, replacement piston o-ring, long

pressure setting screw, instructions manual.

General information

The MaxFlow HPA LP regulator can be used with any standard paintball HPA tank. The recommended input for

the MaxFlow regulator (or the tank regulator output pressure) is 850 PSI. The regulator can work even with lower input

pressure, but full and correct operation cannot be guaranteed. Do not use input pressure higher than 900 PSI.

Installation on an HPA tank

Make sure the pressure setting screw is loose before installing MaxFlow on your HPA tank. It should be

screwed in to the same level as or protruding above the regulator head. The regulator is delivered with the pressure

setting screw loosened, i.e. ready to be installed on your HPA tank. Tighten the regulator clockwise until it is fully

screwed onto the tank. The O-ring on the tank fits tightly around the whole circumference and it is not necessary to

tighten the regulator with great force.

On/Off and pressure adjustment

The on/off and the pressure setting function is performed using an Allen screw located in the head of the

regulator. By slowly screwing the Allen screw clockwise, the tank is opened and then the output pressure of the MaxFlow

LP regulator starts to increase gradually. Tighten the screw until the desired pressure is reached. To reduce the regulator

output pressure or to turn the regulator off, turn the setting screw counterclockwise – however, the pressure in the

regulator will not drop until the higher pressure that is already inside the regulator chamber is released. This can be

achieved, for example, by disconnecting and reconnecting the hose.

The setting screw can be secured with a smaller Allen screw placed sideways in the groove of the regulator's

head. It is necessary to loosen the small locking Allen screw before it is possible to set the pressure again. Never tighten

the locking screw with great force as this may damage the thread of the setting screw.

The regulator operates in the output pressure range of 0–225 PSI. After you turn the regulator off or close the

HPA tank, you can release the pressure inside the regulator chamber by simply inserting an Allen key into the QD

coupler and pressing the check valve.

Removal of the regulator from the HPA tank and reinstallation

The regulator can also be removed from the tank without switching off and releasing the pressure. Pressure

leakage from the regulator occurs when the HPA tank O-ring stops sealing. There is no risk of damage to the O-ring of

the HPA tank when using MaxFlow..

If the regulator is removed from the tank without switching off, the setting screw must be loosened before

installation onto a different tank. Various tanks have various outlets, pin heights, and pin shapes. Therefore the

MaxFlow output pressure may vary.

There is no need to loosen the setting screw when reinstalling the regulator onto the same HPA tank where

MaxFlow was set to the desired pressure and then removed. Once reinstalled, MaxFlow will have the same previously

set pressure.

Safety valve

MaxFlow is equipped with an adjustable safety valve. To adjust it, unscrew the red cover nut counterclockwise.

There is a setting screw for size 9 key (the key is not needed) under the red nut. Turning the screw clockwise increases

the pressure limit at which the safety valve starts releasing the pressure. Turning the screw anti-clockwise reduces the

set pressure of the safety valve.

IMPORTANT: Only manipulate the safety valve when the MaxFlow LP regulator is removed from the

tank! The setting screw must never exceed the edge of the cover nut!

Tournament lock

Once the desired pressure has been set, the regulator can be locked to prevent the change in the output

pressure settings. MaxFlow allows several ways of locking to be used.

1) Destructive sticker with a unique number. This sticker can be used to seal the hole containing the setting

screw, making it impossible to manipulate the setting screw without destroying the sticker. The event organizer will only

note down the unique number of the sticker corresponding to the unique player. Destructive stickers are included in the

package. Replacement destructive stickers can be purchased from our online store or from our partners.

2) Plastic cable ties. After locking the adjusting screw with a small Allen screw in the groove of the regulator's

head, the locking Allen screw can be covered with a plastic cable tie, which is commonly used by the event organizers.

Without cutting the tie, the locking Allen screw cannot be loosened and the pressure setting cannot be changed using the

large setting screw.

3) Standard Tournament Lock. The cap which is put on the head of the regulator and secured against removal

by plastic cable ties. These caps can be printed on a 3D printer and the print file is available at our online store free of

charge.

Maintenance of Max Flow LPR

The regulator must be removed from the HPA tank before maintenance!

1) To disassemble the regulator: First, completely loosen and remove two opposite securing Allen screws from the lower

part of the regulator's head. Then unscrew the regulator's head upwards.

2) Turn the regulator upside down – 10 disc springs and a flat, stainless steel washer fall out.

3) Push the piston out of the regulator body from the HPA tank side.

4) Clean the inside of the regulator body with a cloth* and remove any dirt.

5) Remove the O-ring from the piston using a blunt tool (e.g. using a flat-blade screwdriver) and clean it.

6) Wipe the disc springs and the washer clean.

7) Lubricate the inside surface of the regulator body, which is in contact with the o-ring, with a thin film** all the way to the

inner edge at the regulator outputs’ level.

8) Mount the piston o-ring back on the piston and lubricate around the circumference. Insert the lubricated piston into the

regulator body and slide it in. When sliding the piston in, it is most likely to jam and not hit the center hole. Use a small

Allen key to align it (turn the regulator upside down).

9) Put 5 pairs (10 pieces) of disc springs on a large Allen key according to the diagram. Insert the springs assembled in

this way into the regulator body and remove the key. Then place the last straight stainless steel washer on the springs.

10) Screw the head into the “Assembly check” position on the regulator body and secure it with two Allen screws.

11) Push the piston from the HPA tank side. It should partially slide back and compress the disc springs.

*The cloth can be moistened with alcohol.

**We recommend “TechT Gun Sav” or silicone-based lubricants. WD-40 and similar lubricants, which can damage

the gasket, are not suitable!

IMPORTANT NOTICE

● Never disassemble the regulator while it is mounted on the tank / under pressure!

● Never fully remove the safety valve setting screw while the regulator is mounted on the tank / under pressure!

● Do NOT use with CO2!

● If the basic 8mm setting screw is below the regulator head level by more than 4 mm (4 turns) when set to the

desired output pressure, replace it with the longer 12mm setting crew included.

● All output ports of the MaxFlow regulator can be swapped without deteriorating airflow.

● The regulator can be only used screwed directly to an HPA tank. It will not work with an external ON/OFF valve or

another method of connection!

● MaxFlow uses a unique construction and works directly with the opening pin of HPA tanks. Its flawless

function depends on the condition of the HPA tank output valve – or more precisely the gasket of the tank

opening pin. In case your MaxFlow does not work properly, check the condition of this gasket first
